Overview
The Renesas Electronics Corporation 71V3577S80BGI is a 4.5 Mbit (128K x 36) synchronous single data rate static random access memory IC. It operates with a maximum clock frequency of 100 MHz and features an access time of 8 ns. The device utilizes a parallel interface and requires a supply voltage between 3.135 V and 3.465 V. It is housed in a 119-pin PBGA package measuring 14x22 mm. The component supports surface mount installation and functions within a commercial temperature range of 0°C to 70°C.
Feature Summary
- Supports synchronous single data rate operation for high-speed data transfer
- Provides flow-through output architecture for direct data availability
- Integrates self-timed write cycles with global write control capabilities
Applications
- High-performance networking equipment requiring fast memory access
- Industrial control systems utilizing synchronous logic interfaces
- Telecommunications infrastructure components
Procurement Notes
Verify the current manufacturing status, as this specific part number may be obsolete or end-of-life. Confirm that the 119-pin PBGA footprint matches the target PCB design. Ensure the 3.3V core voltage requirement aligns with the system power rails. Check for RoHS compliance restrictions if applicable to the final assembly environment.
Selection Notes
Select this component when a 128K x 36 organization is required for wide data bus applications. The 100 MHz synchronous speed suits moderate-to-high bandwidth needs. Consider the 119-pin BGA package constraints for board space. Verify thermal management requirements for the specified operating temperature range.
Part Context
This SRAM belongs to the 71V3577 family of 3.3V synchronous memories. It shares architectural similarities with other devices in the series but differs in speed grade and packaging options. The 71V3577S80BGI specifically denotes the 8 ns speed variant in the 119-pin BGA configuration.
Replacement Considerations
The 71V3577S80BGI8 is a reel-packaged alternative from the same manufacturer. Cross-vendor substitutes require verification of pin compatibility and electrical specifications.
